Rereading the comments, one possible issue:

This is, actually, a question for the specification. The last portion of
the primer says
"if the element on which the rel is added has an id or an about, then
the value of that attribute becomes the name of the node, and all
triples are appropriately updated. about takes precedence over id, since
it is an explicit RDFa statement."
which means that, strictly speaking, the id="card" may not be necessary
on the example specfication-wise. But because this is a primer, I think
it is still better to add it there.
